]2.3
ELEVATOR MACHINE
**************************************************************************
NOTE: Use geared traction machines up to nine
floors with moderate-to-heavy traffic demand,
generally not more than three or four cars in a
group and for speeds not exceeding 1.75 mps 350 FPM.
Use gearless traction for speeds beyond 1.75 to 2.00
mps 350 to 400 FPM, for ten floors or more and where
intensive traffic is anticipated, i.e., high-rise
hospitals, busy headquarters, office buildings.
Gearless elevators are often used in large hospitals
for six or more stops. However if 2.00 mps 400 FPM
is required, the elevator industry usually supplies
2.54 mps 500 FPM as the standard entry for gearless
traction machines. Use generator field control for
all applications of gearless elevators and most
geared elevators. For motors greater than 11 kw 15
hp, use power factor correcting capacitors to
increase power factor to minimum 90 percent.
**************************************************************************
Provide elevator machines which are [[worm] geared] [or] [gearless]
traction, direct-drive machines according to ASME A17.1/CSA B44, Section
